Dear Scotty and Edison,
Many thanks for assistance provided.
This afternoon was found the fault,
One cable from main terminal box to choke in excitation system, that was broken inside holding only by the plastic insulation. Wire replaced, shaft tested with load and all ok.
Dear Scotty,
Many thanks for your effort in clearing doubt of fundamental principle.
Until now, this shaft generator was giving trouble as out put voltage found 125 volt /60Hz instead
of 440v/60Hz.
We checked all in according to troubleshooting list:
- Rotary rectifier diodes replaced.
- AVR...
Hi Scotty,
Well noted. Pls find below my idea,
This is a shaft generator.
W10 is connected to choke via terminal 2( purpose not understood) and sorted to Radio
noise suppressor capacitor. Further
it is connected to stationary rectifier and current transformer. The purpose of CT (pos 6) to...
This Avr circuit consist of Choke,Radio noise supressor, protection transformer and static CT.
Kindly assist in how the circuit works.https://files.engineering.com/getfile.aspx?folder=76345ca7-4888-4655-b5e7-f1b0a469d2b2&file=1_D_MAK_MAIN_ENGINE_External_Documents_(C-1-2)_36.pdf
